The professor Ba Dechun from School of Mechanical Engineering and Automation with his research group cooperating with The Chinese academy of sciences Shenyang scientific instruments co., LTD, developed many dry vacuum pump with independent intellectual property rights. This product owes the same quality but a lower price, thus result in a deep price cut among foreignlike products, so as to break the long term international monopoly. The application of this product brings substantial profits to enterprises. According to statistics, this NEU invented dry vacuum pump can respectively reduce water and electricity consumption 31.2% and 27.6%, and the sewage to be disposed reduced 99.5%. All these bring a additional profit to enterprises about 100.3 million yuan RMB, and additional tax revenue 15.3 million yuan RMB, and the total quota of increasing revenue and expenditure reduced is 149.3 million yuan RMB.
For a long time, the R&D and production of dry vacuum pump has been monopolized by few English and German transnational corporations. Relying on import too much, the self sufficiency of China's Chip industry chain faces grave threats. Ba Dechun, cooperating with The Chinese academy of sciences shenyang scientific instruments co., LTD, developed two series, more than 10 kinds of models dry vacuum pump with independent intellectual property rights. After authorities detection, the core specification of this invention reaches the same advanced level of foreign like products, but it is sold with only 70% of the foreign like products prices.
